When baking or cooking something like a sauce that will stick to the pan we spray a release agent in it right? Why not make your own? for years I have made one that is part olive oil and part lecithin. My ratio is to fill my container not quite to the top with olive oil and then put in about one tablespoon of liquid lecithin. I’ve used even the cheap brands of lecithin over the years and it works perfectly. Just shake the mixture really good after putting the lecithin in.
Because the shelf where I keep my cooking release is shallow I do not use a spray bottle but have a 1/4-pint jelly jar as my container and then just pour it as needed.
I use the mixture in my cast iron pans before storing and for cooking. It works great!
